®ICM7243
8-Character, Microprocessor-
Compatible, LED Display Decoder Driver
The ICM7243 is an 8-character, alphanumeric display driver
and controller which provides all the circuitry required to
interface a microprocessor or digital system to a 14-segment
or 16-segment display. It is primarily intended for use in
microprocessor systems, where it minimizes hardware and
software overhead. Incorporated on-chip are a 64-character
ASClI decoder, 8 x 6 memory, high power character and
segment drivers, and the multiplex scan circuitry.
6-bit ASCll data to be displayed is written into the memory
directly from the microprocessor data bus. Data location
depends upon the selection of either Sequential
(MODE = 1) or Random access mode (MODE = 0). In the
Sequential Access mode the first entry is stored in the
lowest location and displayed in the “left-most” character
position. Each subsequent entry is automatically stored in
the next higher location and displayed to the immediate
“right” of the previous entry. A DISPlay FULL signal is
provided after 8 entries; this signal can be used for
cascading devices together. A CLeaR pin is provided to
clear the memory and reset the location counter. The
Random Access mode allows the processor to select the
memory address and display digit for each input word.
The character multiplex scan runs whenever data is not
being entered. It scans the memory and CHARacter drivers,
and ensures that the decoding from memory to display is
done in the proper sequence. Intercharacter blanking is
provided to avoid display ghosting.

Chip Select from µP address decoder, etc.
WR 17 WRite pulse input pin (active low). For an active high write pulse, CS can be used, and WR can be used
as CS.
MODE 31 Selects data entry MODE. High selects Sequential Access (SA) mode where first entry is displayed in
“leftmost” character and subsequent entries appear to the “right”. Low selects the Random Access
(RA) mode where data is displayed on the character addressed via A0 - A2 Address pins.
A0/SEN 30 In RA mode it is the LSB of the character Address. In SA mode it is used for cascading devices for
displays of more than 8 characters (active high enables device controller).
A1/CLeaR 29 In RA mode this is the second bit of the address. In SA mode, a low input will CLeaR the Serial Address
Counter, the Data Memory and the display.
A2/DISPlay FULL 28 In RA mode this is the MSB of the Address. In SA mode, the output goes high after eight entries,
indicating DISPlay FULL.
OSC/OFF 27 OSCillator input pin. Adding capacitance to VDD will lower the internal oscillator frequency. An external
oscillator can be applied to this pin. A low at this input sets the device into a (shutdown) mode, shutting
OFF the display and oscillator but retaining data stored in memory.

Detailed Description
WR, CS, CS - These pins are immediately functionally
ANDed, so all actions described as occurring on an edge of
WR, with CS and CS enabled, will occur on the equivalent
(last) enabling or (first) disabling edge of any of these
inputs. The delays from CS pins are slightly (about 5ns)
greater than from WR or CS due to the additional inverter
required on the former.
MODE - The MODE pin input is latched on the falling edge
of WR (or its equivalent, see above). The location (in Data
Memory) where incoming data will be placed is determined
either from the Address pins or the Sequential Address
Counter. This is controlled by MODE input. MODE also
controls the function of A0/SEN, A1/CLR, and A2/DlSPlay
FULL lines.
Random Access Mode - When the internal mode latch is
set for Random Access (RA) (MODE latched low), the
Address input on A0, A1 and A2 will be latched by the
falling edge of WR (or its equivalent). Subsequent changes
on the Address lines will not affect device operation. This
allows use of a multiplexed 6-bit bus controlling both
address and data, with timing controlled by WR.
Sequential Access Mode - If the internal latch is set for
Sequential Access (SA), (MODE latched high), the Serial
ENable input or SEN will be latched on the falling edge of
WR (or its equivalent). The CLR input is asynchronous, and
will force-clear the Sequential Address Counter to address
000 (CHARacter 1), and set all Data Memory contents to
100000 (blank) at any time. The DISPlay FULL output will
be active in SA mode to indicate the overflow status of the
Sequential Address Counter. If this output is low, and SEN
is (latched) high, the contents of the Counter will be used to
establish the Data Memory location for the Data input. The
Counter is then incremented on the rising edge of WR. If
SEN is low, or DISPlay FULL is high, no action will occur.
This allows easy “daisy-chaining” of display drivers for
multiple character displays in a Sequential Access mode.
Changing Modes - Care must be exercised in any
application involving changing from one mode to another.
The change will occur only on a falling edge of WR (or its
equivalent). When changing mode from Sequential
Access to Random Access, note that A2/DlSPlay FULL
will be an output until WR has fallen low, and an Address
drive here could cause a conflict. When changing from
Random Access to Sequential Access, A1/CLR should
be high to avoid inadvertent clearing of the Data Memory
and Sequential Address Counter. DISPlay FULL will
become active immediately after the rising edge of WR.
Data Entry - The input Data is latched on the rising edge of
WR (or its equivalent) and then stored in the Data Memory
location determined as described above. The six Data bits
can be multiplexed with the Address information on the
same lines in Random Access mode. Timing is controlled
by the WR input.
OSC/OFF - The device includes a relaxation oscillator with
an internal capacitor and a nominal frequency of 200kHz.
By adding external capacitance to VDD at the OSC/OFF
pin, this frequency can be reduced as far as desired.
Alternatively, an external signal can be injected on this pin.
The oscillator (or external) frequency is pre-divided by 64,
and then further divided by 8 in the Multiplex Counter, to
drive the CHARacter drive lines (see Figure 3). An inter-
character blanking signal is derived from the pre-divider. An
additional comparator on the OSC/OFF input detects a
level lower than the relaxation oscillator's range, and
blanks the display, disables the DISPlay FULL output (if
active), and clears the pre-divider and Multiplex Counter.
This puts the circuit in a low-power-dissipation mode in
which all outputs are effectively open circuits, except for
parasitic diodes to the supply lines. Thus a display
connected to the output may be driven by another circuit
(including another ICM7243) without driver conflicts.
Display Output - The output of the Multiplex Counter is
decoded and multiplexed into the address input of the Data
Memory, except during WR operations (in Sequential
Access mode, with SEN high and DISPlay FULL low),
when it scans through the display data. The address
decoder also drives the CHARacter outputs, except during
the inter-character blanking interval (nominally about 5µs).
Each CHARacter output lasts nominally about 300µs, and
is repeated nominally every 2.5ms, i.e., at a 400Hz rate
(times are based on internal oscillator without external
capacitor).
The 6 bits read from the Data Memory are decoded in the
ROM to the 17 (15 for ICM7243B) segment signals, which
drive the SEGment outputs. Both CHARacter and
SEGment outputs are disabled during WR operations (with
SEN high and DISPlay FULL Low for Sequential Access
mode). The outputs may also be disabled by pulling
OSC/OFF low.
The decode pattern from 6 bits to 17 (15) segments is done
by a ROM pattern according to the ASCll font shown.
Custom decode patterns can be arranged, within these
limitations, by consultation with the factory.
